在采用绞吸式挖泥船进行河湖清淤疏浚施工时，通常需串联拉力泵船来加大疏浚泥土的输送距离，为提高施工效率，需合理确定接力泵船的布置位置。结合厦门集美皮划艇赛道清淤吹填工程，提出一种确定接力泵船位置的理论计算方法，该方法是根据泥浆杨程、输送阻力损失、泵串联特性推导出接力泵船位置的计算公式。针对工程实际提出了提高疏浚生产效率的措施，取得了较好施工效果。

In the river dredging by cutter suction dredger,a tandem pump ship is needed to improve the sludge conveying dis-tance and efficiency,so it is necessary to study the reasonable layout of the tandem pump ship. In combination with a dredging and hydraulic filling project of a canoeing race in Xiamen,we put forward a theoretic calculation method to determine the rational layout of the tandem pump ship,which is a formula derived from the relative parameters including the sludge lift,conveying re-sistance loss and tandem characteristics of the pump ship. Some measures that could improve the construction efficiency were pro-vided according to the practical problems.
